Sacrificing Energy for Mass Transfer to Boost Solar Steam Generation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Vapor accumulation often limits the performance of passive interfacial solar evaporation. Inspired by the Dyson sphere concept, Xu, Yang, and co‐workers designed a perforated‐shell evaporator with an internal non‐evaporating core that diverts incident sunlight to drive self‐generated internal convection for vapor removal.

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Molecular Interfacial Chelation Enables Wide‐Temperature Aqueous Zinc‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces a chelating additive for wide‐temperature aqueous zinc‐ion batteries. Methionine‐chelated zinc adsorb onto the Zn(002) plane and release Zn2+ in situ, forming a zinc‐ion‐rich buffer reservoir at the electrode/electrolyte interface, enabling aqueous zinc‐ion batteries to exhibit stable cycling performance over the temperature range

Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.
